SPINNING-SPINDLE AND SUPPORT THEREFOR.

SPECIFICATION forming part of Letters Patent No. 425,930, dated April 15, 1890. Application filed July 25,1889. Serial No. 318,662 (No model.)

To all whom it may concern): present invention; Fig. 2, a section in the Be it known that I, HENRY A. BURLIN- line at ocof Fig.1. Fig.3 shows opposite side GAME, of Central Falls, county of Providence, elevations of the bolster or tube extended State of Rhode Island, have invented an Iminto the spindle-support, and Figs' 4 and 5 5 provementin Spinning-Spindles and Supports show details to be described. 55 Therefor, of which the following description, The rail A has secured to it by nut B a in connection with the accompanying drawcurb 0, having a threaded shank O, the curb ings, is a specification,1ike letters and figures being shown as provided with a cover 0 to on the drawings representing like parts. aid in preventing lint and dust entering the This invention has for its object the procurb and the oil which may be therein. The 60 duction of a novel light running spindle shank of the curb is shown as screw-threaded adapted to yield to variations in load, and internally (see Fig. 1) to receive the shank of thus avoid injurious jar or gyration. the spindle-support Ct, (also shown as thread- Prior to my invention spindle-bolsters have ed, the said threads in engagement one with been provided with ball-like enlargements the other,) besides keeping the support and 65 seated to rock or tip within a surrounding the part 0 together, also affording means for case or sleeve; but in this my invention a the vertical adjustment of the support, and part of the spindle is seated on and rotates by making the threads rather coarse a loose. outside of a ball carried by a spindle-supfit may be made between the said threads, so port, a steadying-pin in line with the center as to permit a limited amount of lateral 70 of the spindle being extended through the movement or looseness to enable the support said ball or into a bolster therein, as will be to move laterally. The support at or near its described. I upper end is provided with a spherical seat My invention consists, essentially, in the a.

"The spindle-body will preferably have a steadying pin or projection, as cl, to extend down into the bolster loosely; but the said pin does not need to rest at its lower end on a step, for the weight of the spindle is carried by the support having the spherical surface. The support a. is surrounded below the whirl with two sleeves or shields e f, one over the other, each of the said shields having oilholes 6 7 and 8 9 10, the partial rotation of the shield f on the shield e uncovering the said oil-holes, so as to permit oil to come into the bolster through the hole 12 by way of the holes 9 and 6, and also additionally into the upper part of the hole 12 by the holes 8 and 5,the oil in the rotation of the spindle following up the said projection (1 over the top of the bolster and of the support a. Should it be desired to cut off admission df oil throughthe openings 5, 8, 9, and 6, a half-rotation of the sleeves e and f would bring the holes 10 and 7 opposite the upper part of the hole 12 and a less amount of oil would be admitted. The

.shield 6 shown as split at 14 from end to end (see Fig. 4) is slipped over the spindlesupport a, between its threaded shank and the under side of the ball a, as shown in .Figs. land 2, and the sleeve f is fitted outside the sleeve 6 and inside the hub 71 of the whirl, the sleeve f receiving part of the wear of the whirl. The openings 5 and, 7 are diametrically opposite each other, as are also the openings 8 and 10. These openings are to aid in regulating or controlling the admission of oil from the box or space inside the curb to the bolster or sleeve and pin (1 or to cut oil? the flow of oil, that depending upon the position of the sleeves and their openingswiiii-i being longitudinally adjustable with.

3. A non-rotating spindle-support (1., having an external ball-like enlargement at its upper end, combined with a spindle having a spherical surface distributed about and supported by the said support cat a point outside the center of rotation of the spindle and resting in contact with said enlargement, substan-' tially as described.

4. A spindle-support having a spherical seat at or near its upper end and having a longitudinal opening, combined with a sleevewhirl spindle having a sphericalsurface to rest on the said support, and with a steadying projection (Z'to enter the said support, substantially as described.

5. A spindle-support having a spherical seat at or near its upper end and having a longitudinal opening and a bolster therein, combined with a sleeve-whirl spindle having a spherical surface to rest on the said support, and with a steadying projection 01 to enter the said support and bolster, substantially as described.

6. A spindle-support having a ball-like upper end, combined with a spindle having a concavcd seat to rest on and surround the said ball-like end to be supported thereby, substantially as described.

7. A spindle-support having a spherical or ball-like upper end and screw-threaded at its lower end and a threaded shank C,into which it is inserted, combined with a sleeve-whirl spindle having a concavity to fit the said spherical orball-like enlargement, the latter supporting the spindle in its rotation, substantially as described.

8. The sleeve-whirl spindle having spherical surfaces 2 3 and a steadying-pin d, and the support having a spherical or ball-like end to sustain the spindle in its rotation, and

a bolster, combined with a pin or projection to restrain the rotation of the bolster with
